CAUTION
Brake pads may contain asbestos, which has been determined to be a cancer causing agent. Never clean the brake surfaces with compressed air. Avoid inhaling any dust from brake surfaces. When cleaning brakes, use commercially available brake cleaning fluids.

See Figures 1, 2, 3 and 4

  1. Remove the brake caliper as follows:
    1. Remove the sliding main pin and sliding sub pin.
    2.  
    3. Remove the caliper and suspend it so the hoses are not stretched. You can use a piece of wire for this. Do not disconnect the hoses.
    4.  

  2.  
  3. Remove the brake pads, anti-squeal shim, support plate and wear indicators. The support plates can be used again provided they have sufficient rebound, no deformation, cracks or wear. Clean them of any rust, dirt and foreign particles.
  4.  

To install:
  1. Check the thickness and runout. Standard thickness should be 0.394 in. (10.0mm) and runout maximum is 0.0059 in. (0.15mm).
  2.  
  3. Install the pad support plates.
  4.  
  5. Install the pad wear indicators plate to each of the pads.

INSPECTION



Using a ruler, measure the pad lining thickness. Standard thickness is 0.374 in. (9.5mm) and minimum thickness is 0.039 in. (1.0mm). Replace the pads if the thickness is not at the minimum or less, or if the pad has severe and uneven wear.
